The full peptide list, A to Z.
This peptide list covers 61 peptides and related compounds, from FDA-approved drugs such as semaglutide, tirzepatide, and tesamorelin to research compounds such as BPC-157, TB-500, and the Khavinson bioregulators. Each one sits in the periodic table below by family, evidence tier, and FDA status, with a plain A-Z index under it, and every tile with a course links straight to it.
A peptide ribbon: amino acid residues linked head-to-tail. From this scaffold come 61 molecules with very different jobs.

Each tile is a peptide. The bar across the top is its family color. Tiles with a course badge open that course.
Every page traces back to the literature
Mechanism, trial evidence, and safety context are sourced from peer-reviewed papers and clinicaltrials.gov, with each claim tagged by tier.
Peptides A-Z questions
Peptides A-Z is a research-first peptide directory that groups 61 peptide and peptide-adjacent compounds by family, evidence tier, FDA status, and course availability.
Entries with tier 1 or tier 2 labels generally have the strongest human evidence, such as approved GLP-1 and endocrine peptides. Animal-only, cell-line, or single-lab findings are labeled separately.
No. Peptides Academy is educational only. It does not sell, prescribe, dispense, or recommend compounds.
Use the evidence tier to separate phase 3 or meta-analysis evidence from smaller trials, observational data, animal models, and cell-line mechanisms before trusting a claim.
No. A few longevity-related molecules, such as NAD+, NMN, and spermidine, are included because readers compare them with peptide topics; their individual pages note the distinction.
Start with the free peptide foundations modules, then use this directory to compare mechanisms, safety context, FDA status, and evidence strength before reading a specific peptide page.
Want a deep dive?
Most of Peptides Academy is mostly free. 26 of the peptides above have a paid mastery course with quizzes, references, and a certificate.
Not medical advice
Peptides Academy is an educational resource. We do not sell, prescribe, dispense, or recommend any compound. Several entries on this page (such as NAD+, NMN, and spermidine) are longevity-related molecules studied alongside peptides but are not themselves peptides; their pages note that distinction. Always consult a qualified clinician before considering any of these compounds.
